    The invention concerns a flexible container (10) for transporting and storing bulk goods (a so-called largesize bag) comprising a shell bottom (12) filling aperture (13) and arranged to be liftable by its upper end, and in the shell (11G) of which have been formed pleats (21), the lower parts of these pleats being folded to be complanar with the bottom. With a view to strengthening the vulnerable region of the bottom and to enabling the manufacturing of the container to be readily automated, the invention teaches closing of the tubular container blank by a seam (20), known in the art, located substantially in the central area of the bottom and folding down the upper plane of the plate into the plane of the bottom and its affixing to the lower plane by a seam. The opposing planes of the pleats may be interconnected by a seam in their marginal area, and they may also be affixed to each other substantially centrally by additional seams, which may be substantially parallel with the seam connecting the lower plane of the pleat to the bottom.

    This invention relates to a flexible container for transporting and storing bulk products.
    The aim of the invention is to increase the strength of the bottom of the container,
    Fig, 1 shows the workpiece; figure 2 - the same, in a perspective view; on fig.Z - flexible container made of the blank shown in figures 1 and 2, in axonometric view} figure 4 - the bottom of the flexible container, bottom view; on fig.Z - flexible container, side view; FIG. 6 is the same, front view.
    A flexible container is made of a tubular blank — which is open at the upper and lower ends. At the upper end of the blank, essentially in the center, an opening 1 is made through which the container is filled. In addition, at the upper end of the billet are made 2, which form a strip-like. Parts 3-6; A flexible container (FIG. 3) is made from a blank (FIG. 2), having a bottom, a loading opening 1 located in the center and lifting lugs formed by the strip-like parts 3-6. The bottom of the container consists of two valves 7 and 8 connected by a seam 9, the connecting seam 9 is located in the central zone of the bottom.
    On the opposite walls of the container there are vertical folds 10, forming in its lower part the valves consisting of the upper 11 and lower 12 planes, superimposed on the bottom of the container and connected by a seam 13, passing along the edge of the planes.
    Planes 11 and 12 can also be joined by additional seams 14, placed parallel to seam 13,
    When the container filled with the bulk product is lifted, the upper plane 11 pulls tight13 .J
    c, and the bottom plane 12 remains free. The maximum load is at the top of the fold 10, which can be defined as the inner top of the bottom of the container. Under loads, the bottom of the container often undergoes rupture, and the gap, as a rule, begins at the top of the fold 10. The greater strength of the bottom of the container offered is ensured by the fact that the edge of the upper 1SHELP 11 is stitched to the edge of the bottom plane 12 and the seam 13
    The strength of the bottom of the flexible container can be increased by attaching opposite planes 11 to 12 through one or more joints of seams 14 in addition to connecting seam 13 (fig. 5 shows the use of two connections to the seams 14, which are located in the central zone of the fold valve 10). The use of connecting seams 14 increases the strength of the bottom so much that not all cases require the use of connecting seam 13 on the edge of the And planes 12. However, the greatest possible strength is It is thawed with simultaneous use of joints 13 and 14,
    The application of the invention allows to significantly reduce the cost of manufacture, because it reduces the number of working steps (no need to make cutouts of bottom strips and fix them), as well as automate the process of making containers (a container can be made, for example, using three automatic sewing machines: one the sewing machine performs the bottom seam 9s and the other two - connecting seams 13 on both sides of the bottom, which fasten opposite planes 11 and 12 ,, to each other
